total outage was 8:45 - 11:15, 2.5 hours
Please process a credit in the amount of $304.50 (75% of SmartT MRC)
Thank you,

Tom,
I forwarded this information to my director and he will advise when he receives an update from engineering.

Subject: Smart T behavior during outages
Pete and I did some testing this afternoon, to determine the
exact behavior the Smart T exhibits during various outage
situations.
We attempted to simulate an Adtran failure and a loop
failure (T1 down).
Adtran failure was simulated by simply turning off the Adtran.
Loop failure was simulated by unplugging the Adtran
from the smart jack.
In both cases, LDMI's switch responded the same way.
When calling any of our numbers during either scenario,
the call would ring 1 time (seemed to be a full ring, not a
half ring) and then would signal a fast-busy.
I was particularly interested in what behavior we would see
on 734-240-0200, as this number is programmed in LDMI's
switch to forward to our off-site answering service in the
event of a busy or no-answer (after three rings). I expected
the switch to see the line as "busy" during a circuit failure
(or Adtran failure) but it did not. It saw an error condition,
and did not forward the 0200 calls to the off-site answering
service.
In speaking with Pete, I understand LDMI uses a DMS
switch. I believe there is functionality in the switch to do
"failsafe" routing. So that if a line is down for whatever
reason, the calls can be automatically routed to a backup
number.
See:
http://www.focal.com/prod_serv/failsafe.html
Implementing this feature would be a good customer service
idea, and could generate extra revenue for LDMI (charge
a small monthly fee for the service).
In any event, we will need to develop a procedure and process
to deal with outages on the T1, such that our customers can
always reach us.
I'm interested in your ideas on how to accomplish this.
Thanks,
Tom
